I was able to sign in on morning, but since 12 o'clock, I'm unable to sign in. However,I was able to sign in only once, but I had to log off because I had to go home. This problem is affected to every instant messenger which uses Windows Live ID for Messenger.
How did it happened?
I was browsing the net usually and safely. All of sudden, WLM popped-out something like this:
WTF!? Okay, it shoud be easy to sign in again... but sign in FAILED. I was only able to sign in at that time when I've by some reason changed password into same password, it worked, but it failed again to sign in and password changing didn't made any success... So, I've tried to check does Messenger even knows that my password is incorrect. I've typed wrong password, and it told it was incorrect. So, my connection is not fault and this is not a cause of my computer.

So I'm not alone... Now, at 20 o'clock, it seems that MS fixed issue and it's possible to sign in. And finally, sign in was successful. This was Microsoft's fault. Let's see are they going to explain this...
